Summary

In unincorporated St. Joseph County, front-yard weeds and rank vegetation over 9 inches violate the county's Weed and Rank Vegetation Control Ordinance, adopted in 2022 under the authority Indiana grants at IC 36-7-10.1-3.

These county ordinances apply to unincorporated areas of St. Joseph County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

The legislative body of a municipality or county may by ordinance require the owners of real property located within the municipality or the unincorporated area of the county to cut and remove weeds and other rank vegetation growing on the property. As used in this chapter, "weeds and other rank vegetation" does not include agricultural crops, such as hay and pasture.

Full Breakdown

Indiana is a Dillon's Rule state, so St. Joseph County's mowing power flows from IC 36-7-10.1-3, which lets a county require owners in unincorporated areas to cut weeds and rank vegetation and set the trigger height. The county's 2022 ordinance fixes that height at 9 inches in front yards, matching South Bend and Mishawaka, and covers unincorporated residential parcels around Granger, Clay Township, and the edges of Osceola. Actively maintained landscaping, agriculture, natural wooded areas, rain gardens, and native or pollinator plantings are exempt, so the rule targets neglect, not choice. Inside South Bend, Mishawaka, and Walkerton, each municipality enforces its own weed limit.

Violations & Fines

Owners get written notice and 10 days to cut or submit a plan; ignore it and the county mows and bills the cost. Repeat offenders face escalating fines of $100, then $200, then $500.

Frequently Asked Questions

How tall can my grass be in unincorporated St. Joseph County?
Front-yard weeds and rank vegetation may not exceed 9 inches under the county's 2022 ordinance. Cultivated landscaping, native gardens, rain gardens, and wooded areas are exempt from the height limit.
What happens if I don't cut an overgrown lot?
The county sends notice and gives 10 days to act. If ignored, it mows the lot and bills you, and repeat violations draw fines of $100, $200, then $500.
